setLayoutKey

Set the context key used to specify an alternate layout to be used instead
of the default layout. Screen content templates can override the layout
template that they wish to be wrapped with by setting this value in the
template, for example:#set( $layout = "MyLayout.vm" )

The default key is "layout", as illustrated above.

Parameters:

layoutKey - the name of the key you wish to use in your
screen content templates to override the layout template
